  • Patent number: 4806213
    Abstract: The invention relates to a method and apparatus for stripping a thin, sheet-like layer of electrolytically accumulated metal precipitate (6) from its supporting structures (1) by means of a peeling blade (4) driven towards the upper edge of the precipitate layer (6). For the stripping operation, the supporting structure (1) is first attached to the stripping station by aid of gripping members (2, 3), the frame whereof advantageously provides a housing in common with the peeling blades (4). Moreover, the measuring and control members (7, 8) which are advantageously located in the common housing, are used in determining the surface profile of the supporting structure (1), and the obtained profile is made use of while choosing the orientation of the peeling blade (4).
